Calibrating minimum counts and catch‐per‐unit‐effort as indices of moose population trend

open access: yesWildlife Society Bulletin, 2016
Monitoring wildlife population trends often involves indices assumed to correlate in proportion to abundance. We used aerial count data and harvest statistics for moose (Alces alces) populations in 16 hunting districts of Montana, USA, spanning 32 years (

Regional African stock markets indices

open access: yesSouth African Journal of Business Management, 2002
This paper presents an overview of the construction of regional indices for three of the four regions within Africa. The three indices are the EASDEX (for East Africa), the NADEX (for North Africa) and the WADEX (for West Africa).

KRAS and GNAS mutations in cell‐free DNA and in circulating epithelial cells in patients with intraductal papillary mucinous neoplasms—an observational pilot study

open access: yesMolecular Oncology, EarlyView.
This study demonstrates that KRAS and GNAS mutations are more prevalent in patients with resected intraductal papillary mucinous neoplasms (IPMN) compared to those under clinical surveillance. GNAS mutations significantly differ between the two patient cohorts, indicating that their absence may serve as a potential biomarker to support conservative ...

Hydrodynamics of undulatory fish schooling in lateral configurations [PDF]

open access: yesarXiv, 2010
The thrust benefits of lateral configurations of two-dimensional undulating fish-like bodies are investigated using high-fidelity numerical simulation. The solution of the Navier--Stokes equations is carried out with a viscous vortex particle method.

Electrocommunication for weakly electric fish [PDF]

open access: yes, 2019
This paper addresses the problem of the electro-communication for weakly electric fish. In particular we aim at sheding light on how the fish circumvent the jamming issue for both electro-communication and active electro-sensing. A real-time tracking algorithm is presented.

On‐treatment dynamics of circulating extracellular vesicles in the first‐line setting of patients with advanced non‐small cell lung cancer: the LEXOVE prospective study

open access: yesMolecular Oncology, EarlyView.
The LEXOVE prospective study evaluated plasma cell‐free extracellular vesicle (cfEV) dynamics using Bradford assay and dynamic light scattering in metastatic non‐small cell lung cancer patients undergoing first‐line treatments, correlating a ∆cfEV < 20% with improved median progression‐free survival in responders versus non‐responders.

Cellular liquid biopsy provides unique chances for disease monitoring, preclinical model generation and therapy adjustment in rare salivary gland cancer patients

open access: yesMolecular Oncology, EarlyView.
We quantified and cultured circulating tumor cells (CTCs) of 62 patients with various cancer types and generated CTC‐derived tumoroid models from two salivary gland cancer patients. Cellular liquid biopsy‐derived information enabled molecular genetic assessment of systemic disease heterogeneity and functional testing for therapy selection in both ...

Use of Sucker-Fishes in Fishing [PDF]

open access: yesNature, 1889
WITH reference to Mr. Sclater's note in NATURE of January 24 (p. 295), on the use of the Remora in fishing, I would like to call attention to the use of sucker-fishes by the aboriginal inhabitants of Cuba. Ferdinand Columbus (“Churchill's Voyages,” 1704, vol. ii. p. 616) says these people used the sucker-fish to Catch both other fish and turtles. These

Fish hemoglobins [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2007
Vertebrate hemoglobin, contained in erythrocytes, is a globular protein with a quaternary structure composed of 4 globin chains (2 alpha and 2 beta) and a prosthetic group named heme bound to each one. Having myoglobin as an ancestor, hemoglobin acquired the capacity to respond to chemical stimuli that modulate its function according to tissue ...
